A Parameter-Free Einstein–Hilbert Coefficient from a Sink-Current Endurance Ledger

Abstract. We derive the Einstein–Hilbert action coefficient parameter-free from the Quantum Traction Theory (QTT) endurance ledger. The QTT-native theorem is a sink-current derivation: axioms A1/A2/A6/A7 fix the space-quantum volume VSQ = 4πℓ3, the tick ẃ = ℓ/c, the mass quantum ṛ = ħ/(cℓ), and force the no-knob constitutive projection gN = (c/ℓ)Jend from endurance flux to acceleration. Combined with the A2 sink continuity law, this gives Newton–Poisson with G = ℓ2c3/ħ. The continuum-geometric layer is stated separately: in a coarse-grained, manifoldlike, distinguishing limit, A1 causal order determines the conformal Lorentzian metric (Hawking–King–McCarthy / Malament), and the QTT four-volume count fixes its…
